Auch ist auf diese Weise eine Ansteuerung des Motors 26 des elektromechanischen Bremskraftverstärkers 12 zum Ausführen eines Brake system adapted so that the at least one pump motor 14 does not promote against the motor 26 of the electromechanical brake booster 12. Also in this way is a drive of the motor 26 of the electromechanical brake booster 12 for carrying out a
(hochdynamischen) Bremsdruckaufbaus in den Radbremszylindern 16 während eines Schließens mindestens eines an den Radbremszylindern 16 (highly dynamic) brake pressure build-up in the wheel brake cylinders 16 during closing of at least one of the wheel brake cylinders 16

Durch die klare Trennung der Funktionen der Steuergeräte 28 und 30 muss der In this case, a division of the functions of the two control units 28 and 30 is realized, which does not require the development of new communication concepts during operation of the two control units 28 and 30. Due to the clear separation of the functions of the control units 28 and 30 of the
elektromechanische Bremskraftverstärker 12 nicht appliziert werden. Somit kann das Bremskraftverstärkersteuergerät 30 einfacher ausgeführt werden, ohne dass dazu Funktionseinbußen des elektromechanischen Bremskraftverstärkers 12 in Kauf zu nehmen sind. Die Herstellungskosten des electromechanical brake booster 12 are not applied. Thus, the brake booster controller 30 can be made simpler without sacrificing the function of the electromechanical brake booster 12. The manufacturing cost of

Beispielsweise kann das Bremskraftverstärkersteuergerät 30 in einem Deckel des Motors 26 des elektromechanischen Bremskraftverstärkers 12 verbaut sein. Es wird darauf hingewiesen, dass eine Ausbildung der beiden Steuergeräte 28 und 30 bevorzugt wird, bei welcher die beiden Steuergeräte 28 und 30 zwar relativ nahe aneinander, aber dennoch als jeweils eigene Bauteile, bzw. als Untereinheiten jeweils eigener Bauteile, vorliegen. Das Hydrauliksteuergerät 28 oder das damit ausgestattete Hydraulikaggregat 10 können zumindest ein erstes Gehäuse 28b aufweisen. Die erste Ansteuerelektronik 28a des In order to ensure a low space requirement of the equipped with the control units 28 and 30 brake system, the hydraulic control unit 28 may be integrated into the hydraulic unit 10. As an alternative or in addition to this, the brake booster control unit 30 may be integrated on / in the motor 26 of the electromechanical brake booster 12, or on and / or in the electromechanical brake booster 12. For example, the brake booster controller 30 may be installed in a cover of the engine 26 of the electro-mechanical brake booster 12. It should be noted that an embodiment of the two control devices 28 and 30 is preferred in which the two control devices 28 and 30, although relatively close to each other, but still as their own components, or as subunits each own components present. The hydraulic control unit 28 or the hydraulic unit 10 equipped therewith may have at least one first housing 28b. The first drive electronics 28a of the
Hydrauliksteuergeräts 28 ist vorzugsweise in und/oder an dem ersten Gehäuse 28b integriert, während das Bremskraftverstärkersteuergerät 30 oder der damit ausgestattete elektromechanische Bremskraftverstärker 12 zumindest ein (anderes) zweites Gehäuse 12a haben. (Die zweite Ansteuerelektronik 30a ist somit in und/oder an dem zweiten Gehäuse 12a integriert.) Das erste Gehäuse 28b kann z.B. ein Gehäuse 28b des Hydrauliksteuergeräts 28 oder des Hydraulic controller 28 is preferably integrated with and / or on first housing 28b, while brake booster controller 30 or the electro-mechanical brake booster 12 equipped therewith has at least one (other) second housing 12a. (The second drive electronics 30a is thus integrated in and / or on the second housing 12a.) The first housing 28b may be e.g. a housing 28b of the hydraulic control unit 28 or the
Hydraulikaggregats 10 sein. Bei dem Bremssystem der Fig. 1 ist das Hydraulic unit 10 be. In the brake system of Fig. 1 is the
Bremskraftverstärkersteuergerät 30 (zusammen mit der zweiten Brake booster control unit 30 (together with the second
Ansteuerelektronik 30a) in das Gehäuse 12a des elektromechanischen Control electronics 30a) in the housing 12a of the electromechanical
Bremskraftverstärkers 12 (als das zweite Gehäuse 12a) integriert. Als Alternative dazu kann das Bremskraftverstärkersteuergerät 30 jedoch auch ein eigenes Gehäuse (als das zweite Gehäuse 12a) haben. Brake booster 12 (as the second housing 12 a) integrated. Alternatively, however, the brake booster controller 30 may also have its own housing (as the second housing 12a).

A transmission speed of an SPI connection / SPI interface created by means of the at least one SPI line 36a and 36b is significantly higher than a corresponding transmission speed of a CAN, an I 2 C or a Flexray data bus. As an alternative to an SPI connection / SPI interface realized by means of the at least one SPI line 36a and 36b, there is also a USB connection / USB interface between the two control devices 28 and 30 via at least one USB line / a USB cable possible. In both cases, much faster communication between the controllers 28 and 30 is ensured than with a conventional data bus connection.
